Certas Energy has expanded its hydrotreated vegetable oil (HVO) depot network to 32 sites, the company has announced.
The HVO supplier has added a number of new supply sites in the last 12 months, with Cambridge Holton Heath, Ipswich and Oban the most recent additions.
The rollout comes ahead of Road Transport Expo (RTX), the premier tradeshow for the road haulage industry, where Certas Energy renewable fuels expert Sam Allen will join a panel to discuss low carbon trucking and the benefits of transitioning to HVO.
RTX 2026 is taking place the NAEC in Stoneleigh, Warwickshire, from 30 June to 2 July.
In June last year, to mark the start of RTX 2025, Certas Energy announced a seven-figure investment in its HVO depot network after growing the network to 28 sites.

Cathy Bailey, energy transition manager at Certas Energy, said: “HVO is a long-term pledge from us to help businesses of all sizes achieve their ESG targets.
“The net zero conversation has changed. Businesses still want to act, but they need solutions that work commercially, operationally and at scale. That’s where HVO plays a critical role.
“Increasing our depot network means HVO is now more accessible to local communities, who benefit from improved air quality due to the reduced emissions compared to standard diesel.
“Customers can plan their transition journey with certainty. In an uncertain world, whether that’s energy prices, regulation or supply chains, what business needs is consistency, an option that reduces emissions today.
“By continuing to invest in HVO, we give customers the confidence and capability to act now, while the wider energy transition continues to evolve.”
According to the DfT, consumption of HVO hit 408 million litres in the first 10 months of 2025 in the UK..
During RTX, Certas Energy experts will be available on stand P4 to welcome attendees keen to explore bulk fuel, HVO, AdBlue and lubricants.
